This study aims to analyse resilience and relational dynamics (competitive, cooperative and co-opetitive) within a triadic buyer-supplier-supplier context. Our central goal is to show how a buyer's supplier-supplier relational behaviour leads to and shapes resilience of this triad. We utilised a multiple-design case approach and selected eight buyers and their suppliers from the textile industry in Turkey. By analysing a triadic context from another industry, we conducted validation analyses. Our findings showed a pattern of relationship between the resilience and the relational dynamics of a triad. Built on theory and insights from the cases, we proposed three propositions. We argued that when co-opetition prevails in a triadic context of relations, the triad resilience level is highest. In competitive relational settings the triad resilience level is lowest, and when the relational dynamics are cooperative, the triad resilience level is moderate. This study is the first to introduce and discuss organisational resilience at triadic level. Furthermore, to our knowledge, our insights from cases are among the first attempts to link three types of supplier-supplier relational dynamics to triad resilience via the use of a multiple-design case approach. Therefore, our contributions are likely to extend the organisational resilience and buyer-supplier-supplier relations research. © 2014 © 2014 Taylor & Francis. Source

The influence of tuning the laser pulse energy during the analyses on the resulting microstructure in a specimen utilizing an ultra-fast laser assisted atom probe was demonstrated by a case study of a binary Al-Li alloy. The decomposition parameters, such as the size, number density, volume fraction, and composition of δ' precipitates, were carefully monitored after each analysis. A simple model was employed to estimate the corresponding specimen temperature for each value of the laser energy. The results indicated that the corresponding temperatures for the laser pulse energy in the range of 10 to 80 pJ are located inside the miscibility gap of the binary Al-Li phase diagram and fall into the metastable equilibrium field. In addition, the corresponding temperature for a laser pulse energy of 100 pJ was in fairly good agreement with reported range of δ' solvus temperature, suggesting a result of reversion upon heating due to laser pulsing. © 2016 Wiley Periodicals, Inc.

Lightweight spatially aware displays (Tangible Magic Lenses) are an effective approach for exploring complex information spaces within a tabletop environment. One way of using the 3D space above a horizontal surface is to di-vide it into discrete parallel layers stacked upon each other. Horizontal and vertical lens movements are essential tasks for the style of multi-layer interaction associated with it. We conducted a comprehensive user study with 18 partici-pants investigating fundamental issues such as optimal number of layers and their thickness, movement and hold-ing accuracies, and physical boundaries of the interaction volume. Findings include a rather limited overall interaction height (44 cm), a different minimal layer thickness for ver-tical and horizontal search tasks (1 cm/4 cm), a reasonable maximum number of layers depending on the primary task, and a convenience zone in the middle for horizontal search. Derived from that, design guidelines are also presented. Copyright 2012 ACM. Source

An in-depth case of an e-Recruiting system implementation is used while focusing on the level of Human Resource (HR) employees to research unintended consequences during the implementation of Human Resources Information Systems (HRISs). We develop a model that integrates the belief and attitude component of the technology acceptance literature with work-related consequences. We provide evidence for an indirect effect of attitudes toward the HRIS on turnover intention that is fully mediated by job satisfaction. Our results contribute to the literature on systems implementations and technology adoption by suggesting work-related outcomes as important additional success variables. © 2013 Elsevier B.V.

Forest fires are known to severely pertubate the nutrient budgets of forested ecosystems by altering the distribution, element species composition and availability of organic matter and associated nutrients. Although several studies have reported on the biogeochemical effects of fires on soil properties and element pools, relatively few have measured the water-flux driven release of nutrients from the forest floor into the mineral soil by lysimeters following low-intensity duff fires. This study was designed to test the effect of a low-intensity fire on the short-term release of nutrients from two different forest floor types developed under a mixed spruce/pine and a beech forest representing the most prevalent forest types in Germany. We found that even low-intensity fires remarkably promoted the amount of leachable nutrients under beech. Compared to the control, the fire treatment at the beech site significantly enhanced the fluxes of DOC by 75%, of DN, NO3-N, NH4-N and DON by, 233, 123, 380 and 158%, respectively, and by 158% for PO4-P. However, at the coniferous site, flux increases were less pronounced exhibiting enhancement rates for DOC of 38%, for DN, NO3-N, NH4-N and DON of 56, 41, 64 and 57%, respectively, and of 19% for PO4-P. Reasons for the different fire effects on the amount and composition of released elements at the beech and conifer site, might be due to the thicker Oa-layer of the coniferous site likely buffering the element pulses into the mineral soil more efficiently, or to the nutrient up-take by the re-establishing ground vegetation. In essence, the study clearly demonstrated that information on the potential range of short-term variability of matter fluxes induced by ecosystem disturbances is necessary, to understand differing filter and trigger mechanisms caused by varying environmental conditions within and between ecosystems. © 2013 Elsevier B.V.
